Six weeks on Wegovy and the scales haven't moved — here's why that happens

Picture where you actually are in the titration schedule

Six weeks in, you've likely just moved onto 0.5 mg or, if your prescriber has taken things cautiously, you're still finishing your first pen. Wegovy's titration path runs 0.25 mg for four weeks, then 0.5 mg, then 1.0 mg, then 1.7 mg, before arriving at the 2.4 mg maintenance dose, with roughly four weeks at each level. That means six weeks in you're at roughly rung two of a five-rung ladder.

The STEP 1 trial, published in the New England Journal of Medicine and the foundation for Wegovy's UK licence, recorded an average weight reduction of around 15% over 68 weeks at the 2.4 mg dose. The meaningful losses in that data were concentrated in the middle and latter phases of the trial, not in the first month or two. Six weeks is genuinely early. The second month on Wegovy is often when people first notice the appetite shift becoming consistent.

It's also worth remembering that the first weeks are designed primarily to reduce the chance of nausea and gut discomfort. Your body is adjusting. That adjustment has a cost, sometimes it means energy going towards tolerance rather than towards fat mobilisation. Give the schedule time to do what it was designed to do.

When six weeks of nothing might signal something worth raising with your prescriber

There's a difference between "slow to start" and "genuinely not responding". Signs worth flagging are: your appetite hasn't changed at all at 0.5 mg, you're finding it no harder to overeat than before treatment started, or you've gained weight despite following the diet and activity guidance. None of those are causes for alarm, they're information for your prescriber.

Some people absorb semaglutide differently. Gastrointestinal conditions, certain medicines and even the timing of injections relative to meals can all play a role. If you're taking an oral contraceptive pill, note that NHS guidance flags the potential for GLP-1 treatment to affect absorption of oral medicines, worth mentioning at your next review. The semaglutide information page covers the broader picture of how the medicine works and what affects its action.

It's also worth pausing on what "no weight loss" means precisely. If you haven't weighed yourself under consistent conditions (same time of day, same day of the week, same amount of clothing) the number can swing by two or three kilograms without any real change in body fat. Weigh yourself once a week, same morning, before eating. If you do that consistently and the number is genuinely flat across six weeks, that's a legitimate conversation for your prescriber.

What often happens between weeks six and twelve

The pattern our prescribers see most often is a delayed start followed by a more noticeable shift once the dose increases. If you're moving from 0.5 mg to 1.0 mg around week eight, many people find the next four weeks more productive than the first six combined. The appetite-suppressing effect of semaglutide tends to become clearer at higher doses, not because lower doses don't work, but because individual threshold responses vary.

There's also a practical reality: eating habits take a few weeks to reorganise around a reduced appetite. Some people unconsciously compensate during the early weeks, choosing calorie-dense foods when hunger does appear rather than lower-calorie options. That's not a character flaw, it's habit. It often corrects itself as the medication's effect on food noise becomes more consistent. The Wegovy overview has more on how the medicine's mechanism builds over time.

If you've been reading about similar experiences and wondered whether the early weeks are the same for everyone, two weeks in and five weeks in are common points where people ask the same question. The short answer is the same at each: early stalls are normal, consistency matters more than speed, and the dose schedule exists for a reason.

The cost question, and where to focus energy instead

A few people at six weeks start wondering whether they should switch providers or look for a cheaper option, especially if the scales haven't moved and the monthly outlay is becoming noticeable. If you ordered before a bank holiday or around a busy period (the post-payday rush in the last week of the month is real), delivery timing can occasionally add to the sense of disruption. That's worth sorting out practically, but it's not a reason to abandon a treatment that may simply need more time.

What is worth understanding is what the price you're paying actually includes. A single transparent cost covering your prescription, clinical review and aftercare support is a different proposition from a headline figure that excludes follow-up. The Wegovy price comparison guide breaks down what different providers typically include and exclude, which is more useful than comparing headline numbers alone.

For most people at six weeks, the right move is not to switch, it's to have a proper clinical conversation. If you're being supported by a prescriber, use that support. If you're not sure what clinical review is included in your current arrangement, our team is available seven days a week, and every repeat order at nume is reviewed by a GPhC-registered prescriber before it's approved. That review includes assessing whether your current dose and approach is still right for you.
